With these controls we can manage the CAD view’s entity references:
From left to right:
·Point reference: When enabled, points are considered in entity referencing. Useful to measure distances between points or drawing on points.
·Final Point reference: When enabled, entities vertices are considered in entity referencing.
·Middle point reference: When enabled, middle points of linear entities segments are considered in entity referencing.
·Near Point reference: When enabled, the nearest vertex to the drawing cursor is considered in entity referencing. Vertex could be final point, middle point or any vertex in a linear entity segment.
·Enable/disable references: Sets if entity referencing should be performed or not.
